Effects of shortening distal shunt catheters in children as relates to patient age and valve type: a simulation study with clinical implications
Shortening the distal catheter leads to increased drainage rates with significant ICP decreases in a 1-year-old child model setup. This effect is more pronounced for low opening pressure valves, unprotected valve systems, and model setups for older children. These results suggest that an SDC may promote overdrainage of variable magnitude depending on the age and height of the child and the valve setting. Therefore, an SDC should be avoided.
